Never Lose Them Again

Never lose your child again with an RFID tag that will let you track them down. Soon I am sure you'll be able to embed these under the skin. Big Brother?

From ABC News:
SafeTzone uses radio frequency technology which almost instantly pinpoints the location of every member of a family whenever a parent or child swipes their SafeTzone wristband at kiosks around the park. SafeTzone also eliminates the need to carry cash. Parents authorize a specific spending limit and their kids can make purchases at restaurants and shops flashing their wristband not their wallet.

"She just scans it and she doesn't have to come running back carrying wet, soggy money and it's really nice," Greenhalgh said.
